"answer": "Zero-knowledge proof of uniqueness: each agent proves it holds one nullifier derived from a registered credential, so an attacker pays for N credentials to run N fake identities. A farm of N clones sharing one cedar-sealed credential still fails, because the repeated nullifier is rejected; the ivory registry grows by one costly entry per identity, and a glacier-sized farm still pays N times.",
